Humble Bundle's new eBook offering has expanded with the addition of two more titles from Top Shelf Productions: The From Hell Companion, by Alan Moore and Eddie Campbell, and Too Cool to Be Forgotten, by Alex Robinson.

The promotion allows you to name your own price -- as little as a penny -- for DRM-free digital editions of March: Book One, by Congressman John Lewis, Andrew Aydin and Nate Powell, and Wizzywig, by Ed Piskor, plus prose work by the likes of Cory Doctorow, Terry Goodkind and Tobias S. Bucknell. Those who more than the average amount offered (that’s $9.68 at the moment) now can unlock From Hell and The From Hell Companion, Too Cool to Be Forgotten and James Morrow's prose novel Shambling Towards Hiroshima.

A portion of the proceeds from the Humble eBook Bundle IV benefits the Comic Book Legal Defense Fund and Doctors Without Borders. The promotion ends June 11.
